Just wondering if there are any red flags when buying a pachinko machine? The one I’m looking at is a Nishijin Power Flash. The seller has it listed as not working stating they dont know how to get it to work (appears to be a pick find as they sell other antiques), there are a few balls there but I was under the impression that it had to be filled with them or the machine wont work also no key. Doesn’t appear to have water damage, also I can’t tell if the pins are bent from the angle of the picture but if some are I’m assuming it’s a pass?
